METHOD OF MAKING SHOES.

APPLICATION HLED'NOV. 21. 1918.

Patented 05011. M, 1921..

this stage being clearly indicated in Fig. 1. The upper at the toe end, and preferably also at the heel end, is next drawn over the last in intimate, contact therewith, worked into the angle between the sideof the last and the projecting margin of the sole and secured to the innersole substantially in said angle by staples D having their bars extending in the direction of the edge of the last. The line of staples at the toe end of the shoe may extend from the tip seam E on one side aboutthe toe to'the tip seam on the other side and preferably a. single staple F is driven at the ball of the shoe on each side of the shoe} The line o-f staples'at the rear end of the shoe may extend from a point Gr adjacent to the heel breast line on one side of the shoe about the'heel to the heel breast line onthe other side of the shoe. A very effectivem'achine for performing'this lasting and stapling operation'is disclosed and claimed in. United States Letters Patent No. 1,117,

- 087,g'ranted November 10, 1914:, upon an application of Adam H. Prenzel, and United States- Letters Patent No. 1,291,754, .granted Jan. 21, 1919, upon an application ofMatthias' Brock, although, of course, the lasting and stapling operations may be effected in otherways and by other apparatus without departing from this invention. v

' ilecha'nism suitable for performing the lasting and stapling step of this method is shown in Fig.- 3 and includes a rest R having astaple clenching face P and a tool T which is also-the nozzle of the stapling mechanism.

Relative movement is effected betw en the rest It and thetool T to cause the tool to last I the upper against; the side of' the last and force it into-theangle between the side of the la t-and the projecting margin of the sole where it is secured, substantially in said angle, by a staple driven through the tool T and clenched upon the facelP of the rest R.

At this stagein'the manufacture of the shoe it is generally desirable to remove the last in order that the sewing of the upper'to the innersole at the sides of the shoe may be more conveniently and effectively performed and: this is particularly desirable when the shank of the last is deeply undercut on the inner side, as is frequently the case particularly in Womens shoes. The last having been removed, the upper is secured by a line l direction of the 1} I of stitches H to the innersole along the side of the, shoe from the point Gr secured by a staple adjacent to'the breast line to the point E secured by a staple adjacent to the tip line, the stitches, therefore, traversing the point F at'the ball of. the shoe which may alsohave been secured by a staple. The sewing operation is repeated upon the opposite side oftheshoe; Iti-s understood, of course, that the sewing may be performed in either h of the-shoe and that under eontfitiens the sewing opera tion may be performed without removing the last from the shoe. Fig. 5 shows diagrammatically mechanism for performing the operation of sewing the upper to the innersole of the shoe with the last removed by means of a straight needle sewing machine, N indicating the needle and S the support for the sole. This operation may be performed by any suitable sewing machine.

Supposing the last to have been removed during the sewing operation, it is again placed in the shoe and the shoe is completed by the attachment of an outsole and heel which may, as shown, he a spring heel. Preferably also a welt is laid over the outwardly extending margin of the upper and is secured by the stitches which also hold the outsole. A shoe thus completed is shown in Fig. 6.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. That improvement in methods of making shoes which consists in assembling upon a last an upper and an innersole having its margin projecting beyond the bottom of the last, staple lasting the toe and heel portions of the upper to the innersole, removing the last, stitching the shoe upper to the sole along the sides of the shoe, rcinserting the last, and completing the shoe in the usual manner.

2. That improvement in the art ofmaking stitchdown shoes which consists in attaching an outturned upper to an innersole by staples and stitches in alternately arranged sections, and then attaching. an outersolle to the upper and innersole by stitches on 3. That improvement in the art of making stitchdown shoes which consists in attaching an outturned upper to an innersole by stitches at the sides of the shoe and by staples at the ends of the shoe, and then attaching an outersole to the upper and innersole by stitches extending about the periphery of the shoe.

4. That improvement in the art of making stitchdown shoes which consists in lasting and attaching an outturned upper to the sole about the toe and heel portions of the shoe while the shoe is on the last, removing the last, and sewing the portions of upper between the lasted portions to the innersole. 5. That improvement in methods of making shoes which consists in assembling upon a last an unmolded upper and an innersole having its margin projecting beyond the bottom of the last, staple lasting the toe portion of the upper to the innersole, removing the last, securing the shoe upper to the sole along the sides of the shoe by non-metallic means, reinserting the last, and completing the shoe in the usual manner.

6. That improvement in the art of makmamas a ing stitchdown shoes which consists in attaching taching an outturned u per to a sole by staples and stitches in a ternately arranged sections about the periphery of the shoe, the toe section being stapled, then applying a welt to cover the staples sewing the welt to the upper and sole;

That improvement in the art of making stitchdown shoes which consists in at taching an outturned upper to a sole by stitches at the sides of the shoe and only by staples at an end of the shoe, then applying a'welt over the staples and stitches and atthe welt, upperand sole together by a continuous line of stitches.

8. That improvement in the art of making stitchdown shoes which consists in lasting and attaching an outturned upper to the sole about the toe of the shoe while the shoe is on the last, then removing the last and sewing the upper to the innersole at the sides only of the shoe.

9. That improvement in the art of mak ingstitchdown shoes which consists in attaching sections of an outturned upper to the innersole by staples only, and in at taching other sections of the upper to the inand stitches and applying a welt to stitches and sewing the welt tothe upper nersole by stitches only, the sewed sections being at the sides of the shoe. I

10. That improvement in the art of making stitchdown shoes which consists in attaching an outturned upper to the sole by lasting and stapling it about the toe and at single points on opposite sides of the ball in the angle between the side of the last and the projecting margin of the sole, securing the upper to the sole by stitches from the lasted portion at the tip line to the heel breast line, then applying a welt stitchesv and connecting the welt, upper and sole together by a continuous line of uniform fastenings.

11. That improvement in the art of making stitchdown shoes which consists in lasting and stapling an outturned upper to the sole about the toe, sewing the outturnecl up per to the sole at the sides of the shoe, then cover the staples and and sole.

In testimony whereof I have signed my \name to this specification.
